New Delhi: Congress today alleged a scam of Rs 45,000 crore in the allocation of mines in Rajasthan and demanded the immediate resignation of Chief Minister Vasundhara Raje along with a Supreme Court-monitored CBI probe into the matter.

Months after the party led a clamour for her sacking over the Lalit Modi row, Congress held Raje 'guilty' for the allocation of as many as 653 mines in alleged contravention of Centre's policy.

The opposition party also questioned the continued silence of Prime Minister Narendra Modi in this regard despite his assertion that he would neither take bribe and nor allow anybody to practise corruption.

At a joint press conference at AICC headquarters, PCC Chief Sachin Pilot, Rajasthan CLP leader Rameshwar Dudi and Chief Congress spokesperson Randeep Surjewala alleged that the trail in the alleged scam reaches the doorstep of the Chief Minister, though only a top official has been arrested in the case.

Pilot and Dudi said that the arrest of Principal Secretary (Mines) Ashok Singhvi was significant given that he had held the same position during Raje's previous term. They accused Raje of causing a loss of Rs 45,000 crore to the state exchequer by allocating 653 mines in Rajasthan on 'first-come-first-served' basis without following transparent procedure and by not auctioning them.

This was done despite the Centre telling the state not to do so until the policy in this regard had been formulated, they further claimed. "This is the biggest scam in Rajasthan. This is the biggest loot in Rajasthan. We demand a CBI probe monitored by Supreme Court. We also demand that the Chief Minister immediately step down as an independent probe is not possible till she holds the post," Pilot said even as he rejected a probe currently being pursued by the Rajasthan Anti-Corruption Bureau.
